Why do babies need TONS of sleep

282 viewsBiologyOther

Okay so this has always perplexed me. It’s not so much a question of why babies need sleep. I understand why everyone needs sleep. Put simply, their bodies grow and repair themselves. However, I’ve been told by many parents that they put their babies to bed at 7:00PM and they are supposed to sleep until around 7:00AM. What I have found, however, is that most of the same parents also complain that their babies are waking up waaay too early. My roommates, specifically, have been dealing with their baby waking up at 4:30AM very consistently.

I have studied the mechanics of sleep (cycles, stages, conditions, etc) on account of my narcolepsy. The science doesn’t add up here, but I am certainly not a pediatrician. To compound the issue, they also put their babies down for naps that are often a couple hours long. Wouldn’t this be counter-intuitive? Babies should have a circadian rhythm, and their bodies should naturally know when they are ready to be awake. Is this really the correct course of action for a baby? Why do babies need so much sleep?

Best advice I received as a parent of a newborn “the more they sleep…..the more they sleep”

Scheduled naps are the way. My kids would wake up at 7am then promptly at 9am back to bed for a nap. Then another at 1pm. Back to bed at 7pm.

Even a full term baby isn’t actually ready to be born yet, but b/c the mother has reached her max in terms of resource depletion and pelvic width to accommodate baby, contractions start.

The female human body has spent thousands of years trying to find a “Goldilocks zone” between mother and baby’s needs, and around 40 weeks seems to be it.

The amount of sleeping is merely a continuation of gestation, only outside the womb.
